About this product
An I2C expansion module built around the PCF8574T 8-bit remote I/O expander chip, adding eight general-purpose I/O pins over a two-wire I2C bus. Up to 8 modules can share the same bus, providing up to 64 I/O ports, which helps when a microcontroller runs short of pins.

What I2C address does it use?
The PCF8574 responds on addresses 0x20 to 0x27, selected by its A0, A1 and A2 address pins. Check the board silkscreen and address pads or jumpers to see how the address is set on your module.
How do I wire it to my board?
Connect SDA and SCL to the I2C pins of your board, then connect VCC and GND. The working range is 2.5 to 6 V, so match the supply and logic level to your board. Many modules include pull-up resistors, so avoid adding extra pull-ups unless your module needs them.
